Steton,

If you need to be able to tip, you should look at integrating with GO TAB—they handle gratuities. 

Chandra,

This will be much improved in the near future when we release our new and improved EMAIL CAMPAIGNS project.

Thanks,
Tim

Steve,

You can do this, you just need to change it to a "FIXED" price of $5 instead of "HOURLY"

Thanks,
Tim
